... Si9130 Vishay Siliconix 3.45ADJ DESCRIPTION OF OPERATION The Si9130 is a dual step-down converter, which takes a 5.5-V to 30-V input and supplies power via two PWM controllers (see Figure 1). These 5-V and 3.3-V supplies run on an optional 300-kHz or 200-kHz internal oscillator external sync signal. Amount of output current is limited by external components, but can deliver greater than either supply ...

... Below this threshold, the 5-V controller is shut off. Si9130 is capacitor The frequency of both PWM controllers is set at 300 kHz when the SYNC pin is tied to REF. Connecting SYNC to either GND or V sets the frequency at 200 kHz. L 4.5 V STANDBY ON FIGURE 2. Si9130 Block Diagram Vishay Siliconix linear regulator 3.3-V BST 3 PWM DH 3 ...

... Si9130 Vishay Siliconix OPERATIONAL MODES PWM Mode The 3.3-V and 5-V Buck controllers operate in continuous-current PWM mode when the load demands more than approximately 25% of the maximum current (see typical curves). The duty cycle can be approximated as Duty_Cycle = V In this mode, the inductor current is continuous; in the first half of ...

... Oscillation frequency should be set at 200 kHz and increase the output capacitance to 660 mF on the 5-V output to maintain stable performance load current. Operation on the 3.3-V supply will not be affected by this reduced input voltage. Si9130 Vishay Siliconix V REF (2)(p)(GPWP ...
